Full textHierarchical segmentation has been a model which both identifies with the construct of extracting a tree structured model of the image, while also interpreting it as an optimization problem of the optimal scale selection. Hierarchical processing is an emerging field of problems in computer vision and hyper-spectral image processing community, on account of its ability to structure high-dimensional data. Chapter 1 discusses two important concepts of Braids and Energetic lattices. Braids of partitions is a richer hierarchical partition model that provides multiple locally non-nested partitioning, while being globally a hierarchical partitioning of the space. The problem of optimization on hierarchies and further braids are non-tractable due the combinatorial nature of the problem. We provide conditions, of h-increasingness, scale-increasingness on the energy defined on partitions, to extract unique and monotonically ordered minimal partitions. Furthermore these conditions are found to be coherent with the Braid structure to perform constrained optimization on hierarchies, and more generally Braids. Chapter 2 demonstrates the Energetic lattice, and how it generalizes the Lagrangian formulation of the constrained optimization problem on hierarchies. Finally in Chapter 3 we apply the method of optimization using energetic lattices to the problem of extraction of segmentations from a hierarchy, that are proximal to a ground truth set. Chapter 4 we show how one moves from the energetic lattice on hierarchies and braids, to a numerical lattice of Jordan Curves which define a continous model of hierarchical segmentation. This model enables also to compose different functions and hierarchies

Full textIn the context of greenhouse gas emissions and fossil and fissile resources depletion, solar energy is one of the most promising sources of power. The amount of renewable energies in the future energy mix depends on their availability, on their cost and on their level of efficiency. Various issues still limit the development of the solar energy. Among them, the temperature elevation into the module induces an efficiency degradation of 12% in standard cases. In spite of this statement, the actual solar module structure has not changed since its creation in the seventies, and the technologies are still evaluated at room temperature. The objective of this thesis is to study the impact factors which govern the module temperature elevation in order to identify ways to apply a significant reduction. A multi-physics modeling is built in order to predict the module behavior depending on the environmental conditions. The thermal modeling is grounded on the radiation into participating media. This feature leads to the determination of generalized Fresnel equation for absorbing media. It allows us to determine a spectral and hemispherical value of the glass emissivity. The optical-electrical-thermal modeling has been compared to measurement in real conditions and is able to predict the module behavior over a one-day period. It allows the evaluation of the gain obtained by optimizing the module components. A parametrical study identifies several improvements to lower the module operating temperature. The PhD work includes a state-of-the-art study (chapter 1), a study of the radiation heat transfer at PV module scale (chapter 2), the details of the multiphysics modeling (chapter 3), the study of the PV module through the modeling (chapter 4), a parametrical study (chapter 5) and a conclusion (chapter 6)

Full textThis work tries to approach the problem of the energy transition under a rather particular angle to raise the complexity of this transition and the fact whom we are still relatively far from handling this question in a suitable and convincing way. By discuss this problem in the first two chapters, basing on the already existing literature ; two other models were proposed to contribute modestly to this literature. These two models belong to two different families, in particular TETM and EnvETM2 who have, each, peculiarities appropriate to him, and give, generaly, rather divergent results.We deduce from results of the first model that the development of the renewable energies does not have to exceed certain level, and that the policies based on energy prices (taxes, subsidy, ...) will be more effective to accelerate the energy transition. The energy transition will not can pass with the same rhythm in all sectors, what makes that political choices must be very precise to choose the rignts sectors ans territories, to lead an optimal transition.The second model, has for objective the generalization of the model of CMM1 to explore new policies to fight against the environmental problems, caused by the massive use of the fossil energy resources, sources of GHG (greenhouse gas emissions). We can summarize the results of this model by deducing that the renewable energy must be produced over time, even with an energy price lower than its marginal cost. This implies that the renewable energies have to subsidized, as long as they remain non-competitive. The use of the renewable energies is not sufficient solution to fight against GHG emissions, in certain case we have to abate as we use ReE

Full textThe present work deals with the parameters optimization of tuned mass dampers (TMD) used in the control of vibrating linear structures under stochastic loadings. The performance of the TMD device is deeply affected by its parameters that should be carefully chosen. In this context, several optimization strategies can be found in the literature and among them the stochastic structural optimization (SSO) and the reliability based optimization (RBO) are particularly addressed in this dissertation.The first part of this work in dedicated to the calculation of the optimal bounds solutions of the TMD parameters in presence of uncertain but bounded (UBB) structural parameters. The bounds of the optimal TMD parameters are obtained using an approximation technique based on Taylor expansion followed by interval extension. The numerical investigations applied with one degree of freedom (1DOF) and with multi-degree of freedom (multi-DOF) systems showed that the studied technique is suitable for the SSO strategy and that it’s less appropriate for the RBO strategy.As immediate consequence of the obtained results in the first part of this work, in the second part a method, called the continuous-optimization nested loop method (CONLM), providing the exact range of the optimal TMD parameters is presented and validated. The numerical studies demonstrated that the CONLM is time consuming and to overcome this disadvantage, a second method is also presented. The second method is called the monotonicity based extension method (MBEM) with box splitting. Both methods have been applied in the context of the RBO strategy with 1DOF and multi-DOF systems. The issue of effectiveness and robustness of the presented optimum bounds of the TMD parameters is also addressed and it has been demonstrated that the optimum solution corresponding to the deterministic context (deterministic structural parameters) provide good effectiveness and robustness.Another aspect of RBO approach is dealt in the third part of the present work. Indeed, a new RBO strategy of TMD parameters based on energetic criterion is presented and validated. The new RBO approach is linked to a new failure mode characterized by the exceedance of the power dissipated into the controlled structure over a certain threshold during some interval time. Based on the outcrossing approach and the Rice’s formula, the new strategy is firstly applied to 1DOF system and exact expression of the failure probability is calculated. After that, a multi-DOF system is considered and the minimum cross entropy method has been used providing an approximation to the failure probability and then the optimization is carried out. The numerical investigations showed the superiority of the presented strategy when compared with other from the literature

Full textUniventricular hearts are congenital heart diseases, not compatible with life. Fontan transformed the prognosis of these patients by restoring a passive pulmonary circulation. Unfortunately, the long-term prognosis remains pejorative. To reduce the morbidity and mortality of these patients, we developed a surgical preconditioning protocol, allowing a percutaneous Fontan totalization, adaptive to pulmonary resistance and to the working capacity of the ventricle. We observed that the mitochondrial respiratory chains do not have the ability to adapt their energy production toward work. The desequilibrium of the Nitroso-redox balance will generate mitohormesis and hormesis, then will inevitably occur a poorly adaptive myocardial remodeling. The only way to improve the long-term prognosis of these patients is to increase the myocardial oxidative capacities of the single ventricle or to create a pulmonary pump
